Rockal Rock-Ponic Blocks

Description

Rockal rockwool blocks provide a high-quality rockwool alternative for hydroponic and
indoor cultivation. The Cubes are a good size for transition planting or finishing small plants,
and they feature a standard-size rockwool macro-plug cutout for easy transplanting of
seedling starts. We offer these rockwool blocks for sale individually so you can purchase
the right amount to fit your needs.

features

High-density material offers ample support and water retention for plants of any size, and ensures that the blocks will maintain their shape during handling. Sterile, UV-blocking wrapper protects roots and fits tightly to keep water and nutrients in the root zone. Specially-developed wetting agent provides efficient, uniform saturation and optimized nutrient uptake with a water holding capacity of 85-95%. Pre-cut squares ensure perfectly uniform, repeatable spacing for grow blocks-no measuring or guesswork required. Rockal Blocks are manufactured from at least 70% recy- cled material.

Advantages

Excellent water holding capacity Higher substrate volume for extra root growth Uniform WC and EC throughout the block Improved control and steerability Solid base for top-heavy plants Larger yields.
